摘要:
针对调谐质量阻尼器（TMD）只对某个频率控制有效果，并且TMD质量和体积较大，不适合应用于处在复杂海洋环境中海洋平台结构的问题，在对TMD应用于海洋平台的减震进行充分研究之后，提出了在海洋平台结构上采用多个调谐质量阻尼器（MTMD）进行减震控制，分析MTMD对海洋平台结构的振动控制效果。以JZ202海洋平台为研究对象，采用并联的形式将多个不同的TMD与海洋平台结构相连，通过输入3种地震波，观察施加不同MTMD的海洋平台体系的位移及加速度反应，并对MTMD系统的基本特性进行研究。结果表明：TMD的质量对海洋平台减振效果有着较大影响，在已知质量系数的前提下，MTMD的阻尼系数和TMD的个数对控制结构的振动起着重要影响，而且这些参数存在优化问题。
Abstract:
In the light of the problems that tuned mass damper (TMD) only had the effect on a frequency control, and TMD’s mass and volume were large, that was not suitable for application to the offshore platform structure in complex environment.Therefore, authors made full research on the TMD applied in offshore platform, and put forward the use of multiple tuned mass dampers (MTMD) in the offshore platform structure to control the vibration, and analyzed the vibration control effect of the MTMD on the offshore platform structure. The JZ20-2 offshore platform was used as the study object, and several different TMDs were connected in parallel to the offshore platform structure. By inputting three different seismic waves, the displacement and acceleration responses of the offshore platform system with different MTMD were observed. The basic characteristics of MTMD system were studied. The results show that the quality of TMD has a great influence on the offshore platform. On the premise of a known quality factor, damping coefficient of MTMD and the number of TMD have important effects on vibration control of structures, and these parameters exist an optimization problem.
